Replace the benchmarking data files and bump version to 0.9.19.

Replaced the benchmarking data files that came from chromium.org with
three files obtained from other datasets on GitHub. Since this repo
is vendored into the chromium/src repo it was occasionally confusing
people who thought the data was actually used for non-benchmarking
purposes and thus updating it for whatever reason.

No code changes.

+# JSON5 Benchmarking data
+
+This directory contains a simple command line program that compares the
+speed of JSON5 with the builtin JSON decoder. 
+
+On a 2018 Mac Mini with a 3 GHz 6 Core Intel Core i5 and 64 GB of memory
+running MacOS 14.2.1, JSON5 is from 800-1200x slower than JSON.
+
+The three datasets come from MIT-licensed data grabbed off the web on
+Mar 3, 2024 around 21:30 GMT. Their accompanying licenses are contained
+in the [LICENSE](license.md) file.
+
+[64KB-min.json](64KB-min.json) was retrieved from 
+<https://raw.githubusercontent.com/MicrosoftEdge/Demos/e3b81daee151a225c1d8f24bf82d31c464b0f737/json-dummy-data/64KB-min.json>.
+It looks like that is part of a set of sample data used to benchmark
+Microsoft Edge's JSON viewer, and I'm guessing that the data was 
+synthetically generated.
+
+[bitly-usa-gov.json](bitly-usa-gov.json) was retrieved from 
+<https://raw.githubusercontent.com/wesm/pydata-book/b992071876bb4324b0323170061c886760289d4d/datasets/bitly_usagov/example.txt>.
+and is a data set that was part of the sample data for *Python Data Analysis,
+3rd Edition*. Apparently this data came from bit.ly data for USA.gov, although
+I have been unable to find either the original source data or a description
+of the schema for it. The book only references the 'tz' field, which appears
+to be a timezone, the 'a' field, which loooks like a web browser User-Agent
+string. The data was originally a file of newline-separated JSON records,
+but I merged them into a single array.
+
+[twitter.json](twitter.json) was retrieved from 
+<https://raw.githubusercontent.com/miloyip/nativejson-benchmark/5dbf5a933a850652bf059cde64cc1f0c8d2c5d6f/data/twitter.json>.
+It comes from what appears to be a a repo used for benchmarking for various
+Native C/C++ JSON parsers. I do not know where this file was retrieved from
+or what the schema is, but this file has a more complicated schema and contains
+data in multiple languages.
